Abstract

Quantitative zooplankton samples were obtained by vertical tows with a Juday plankton net, in the southern Kara Sea, from November 28 to December 11, 2005 (by an expedition of the Murmansk Marine Biological Institute KSC RAS aboard the nuclear ice-breaker “Soviet Union”). The most abundant meroplankton forms were juveniles of Bivalvia and larvae of Polychaeta (the maximum abundances were 106.2 ind/m3 and 7.5 ind/m3, respectively). The results are discussed in relation to changes in the thermal regime of the Arctic Ocean observed during the recent decades.
